Title: Improvements in and relating to protective arrangements for alternating current systems
IPC: H02H1/00
Filed: 1924-01-15
Abstract: 232,324. British Thomson-Houston Co., Ltd., and Fitzgerald, A. S. Jan. 15, 1924. Addition to 193,434. Cut-out arrangements.-In balanced circulating current protective systems as described in the parent Specification employing biassed transformers of the type described in the parent Specification and Specification 216,254, means are provided for compensating for the resistance of the pilot wire circuit. As shown in Fig. 1, one end of a feeder 11 is provided with a biassing transformer 14 having non-inductively related restraining and primary windings 15, 16<b> in the circulating current circuit 13 fed from series transformers 12 at the ends of the feeders. Each transformer 12 also supplies a second primary winding 16a in series with a resistance 18, equal to the resistance of one pilot wire, windings 16<a> and 16<b> being wound in opposite senses. The secondary winding 17, which is inductively related to both primary windings, is connected to the relay 19 controlling the circuit of the trip exit 21 of circuit-breaker 22. On heavy through currents no operation of this relay occurs, the fluxes of the primary windings neutralizing each other so that the resistance of the pilot wires is compensated for. Also the restraint exerted by the winding 15 prevents operation due to out-of-balance currents arising from differences in the transformer characteristics. If, however, a fault occurs in the feeder 11 the difference between the currents in windings 16<a>, 16<b> will be sufficient to operate the relay in spite of the restraining effect. The application of this arrangement to a three-phase feeder is also described. In modified arrangements the restraining winding 15 may be connected in the circuit of primary winding 16<a> (Fig. 2), or it may be divided in two sections each in series with one primary winding (Fig. 3).

A vehicle cleaning installation comprises a driveway D along which vehicles are driven in a direction A, and three sequentially arranged cleaning units 1, 9, 13; unit 1 consisting of a rotatable horizontally mounted brush 2 movable along inclined tracks 3 at each side of the driveway and having spray means associated therewith supplied through pipe 8; unit 9 consisting of a pair of spaced rotatable brushes 10 pivoted about axes inclined slightly from the vertical so that the brushes are biased towards each other, these having spray means associated therewith supplied by pipe 12; and unit 13 consisting of a rotatable horizontally mounted brush 15 movable along inclined tracks 14 on each side of the driveway and having spray means associated therewith supplied through a pipe 18, the installation also including initial and final spray arches 19, 20 supplied through pipes 21, 22. Arranged longitudinally of the installation are photo-electric cells U, V, W, X, Y and Z which control the operation thereof as follows: A vehicle driven in direction A will intercept cell U thereby opening a solenoid to feed arch 19, interception of cell V will take over the duty of U and the solenoid will not be closed until V is by-passed. Cells Y and Z operate in a similar manner to control arch 20. Interception of cell W energizes brush motors 11 and 16 and allows water to be supplied to the spray means associated with the brushes 10 and 15. Interception of cell X energizes brush motor 4, allows water to be supplied thereto and releases a brake so that brush 2 moves down tracks 3 since it is heavier than its counterweight 5. Vehicle interception of cell 7 or brush contact with the vehicle causing brush pivoting will temporarily re-apply the brake thereby causing the brush to follow the rear end contours of the vehicle. At its lowest extreme brush 2 operates a raising motor 23 to lift it back up the tracks 3. As the vehicle contacts brushes 10 a microswitch is operated so that after the brushes are subsequently released the motors 11 and water supply are cut off. When the vehicle contacts brush 15 a brake is released and the brush moves up tracks 14 under the action of a counter-weight 17. At the top of its tracks and after the vehicle has passed, a motor 24 causes the brush 15 to return to its lowermost position to await a further cleaning operation.
